At the risk of looking like a COMPLETE idiot (not the first time, by the way) I'm going to ask this. Just bought a LNIB Beretta Nano last night, and was wondering what the heck is the little cup for that comes in the box? It has the Beretta logo on both sides, and is Beretta blue, like the box itself, but I can't see any purpose for it. Inquiring minds want to know......
